What beliefs would we consider reasonable for a self proclaimed Christian to hold?

Bold added. These are examples of adaptation, not evolution, there was no species change here. The birds are still birds, fish are still fish, reptiles are still reptiles etc.

"Species change" is not the only measure of evolution.  A greater population with physical traits that would have been unusual a few generations before also qualifies.
But yes, species change is being measured in short spans, most often as a result of environmental changes.

"Most recently, evolutionary biologist Yoel Stuart found that green anole lizards on islands in Florida’s Indian River Lagoon needed just 20 generations to adapt to an invasion of brown anoles. Driven to higher perches by the invaders, the green anoles became better at clinging to branches by developing larger toepads with more scales — in just 15 years. It’s more evidence of “evolutionary change on observable time scales,” says Stuart, now at the University of Texas at Austin."

As I understand it that only represents a change of expression of already available traits. Isn't a species typically defined by the ability to produce non-sterile offspring? I would assume that the mating of a current generation of green anoles with those having the genetic make-up of 15 years ago would still produce viable fertile offspring.
